The emacs-daemons we use, which is the melpa-stable version, is very old (a=
bout 6 years out of date), and has a bug caused by a string handling issue.=
 This occurs when "Daemons Always Sudo" is set to on, which is required if =
you want to view the system processes of shepherd, rather than your home pr=
ocesses.

Recipe:

1. Use "customize-group daemons" and set "Daemons Always Sudo" to "on". Sav=
e and set, or set for the session.
2. M-x daemons.

This will throw an error along the lines of

```
Operation on Daemons Always Sudo: 0
cd: No such directory: /sudo::/tmp/tmp.NyPiPKi1eL

```

If you look into this, you'll discover that function "daemons--sudo" does n=
ot trim the newline off the end of the result when it calls "daemons--shell=
-command-to-string". A slightly modified version like so will work (the sam=
e, but with string-trim inserted):

```
(with-eval-after-load 'daemons
  (defun daemons--sudo ()
    "Become root using TRAMP (if on local system).

Switches to a temporary directory to minimise damage potential.

Note that this only works on the local system, not remote systems.  For a r=
emote
system you need to specify your own TRAMP path with a privileged user.

e.g. /ssh:me@HIDDEN|sudo:example.com:"
    (unless (daemons--using-tramp-path-p default-directory)
      (let ((tempdir (string-trim (daemons--shell-command-to-string "mktemp=
 -d"))))
        (cd (format "/sudo::%s" tempdir))))))
```

I wanted to reach out to the author/maintainer and find out if he was plann=
ing to tag another release for melpa-stable, but I don't have a github acco=
unt and don't allow github javascript. I was unable to find any other conta=
ct information for him. Maybe somebody who uses github would want to reach =
out to him. Or if not, maybe we would want to patch the stable version.
